    - by Newbie
    I have List<Attributes> la = new List<Attributes>(); la = (from t in result let t1 = t.AttributeCollection from t2 in t1 where t2.AttributeCode.Equals(attributeType) let t3 = t2.TimeSeriesData from k in t3.ToList() where k.Key.Equals(startDate) && k.Key.Equals(endDate) select new { AttributeCode = attributeType, TimeSeriesData = fn(k.Key, k.Value.ToString()) }).ToList<Attributes>(); I am getting the error: 'System.Collections.Generic.IEnumerable<AnonymousType#1>' does not contain a definition for 'ToList' and the best extension method overload 'System.Linq.Enumerable.ToList<TSource>(System.Collections.Generic.IEnumerable<TSource>)' has some invalid arguments I understood tye error meaning but how to type cast it. I have used var and then iterating over it got the result. But without that any other way by which I can do it? Using C# 3.0 Thanks

  • How do I "think in AngularJS" if I have a jQuery background?

    - by Mark Rajcok
    How do I “think in AngularJS” if I have a jQuery background? Suppose I'm familiar with developing client-side applications in jQuery, but now I'd like to start using AngularJS. Can you describe the paradigm shift that is necessary? Here are a few questions that might help you frame an answer: How do I architect and design client-side web applications differently? What is the biggest difference? What should I stop doing/using; what should I start doing/using instead? Are there any server-side considerations/restrictions? I'm not looking for a detailed comparison between jQuery and AngularJS.

  • wxPython formatting questions

    - by Kevin
    I have an app I was working on to learn more about wxPython( I have been primarily been a scripter ). I forgot about it now I am opening it back up. It's a screen scraper, and I have it working almost the way I want it, going to build a regex parser to strip out the links in every scrape that I don't need. The questions I have are this. In it current state, if I check more than one site, it goes out and scrapes, and returns it in separate windows, the for:each section in the Clicked function. I want to put them in a frame, in the window, altogether. I also want to know if I can take the list they are read into and send it to a checklist, so someone could check off separate items, I want to build a save function and keep certain ones. In regards to a save function, I want to keep saved checks, are there calls to the widgets to save their states? I know it's a lot, but thanks for the help.

  • Settings cell selected background view removes backgroundview

    - by Chris
    I'm trying to set up custom UITableViewCells. I can set the backgroundView no problem, but if I set selectedBackgroundView, the cell's background becomes white and only the selected background is seen: - (void) createCell: (UITableViewCell*)cell onRow: (NSUInteger)row { UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cell_background_red.png"]]; cell.backgroundView = bgImage; cell.selectedBackgroundView = bgImage; cell.textLabel.hidden = YES; UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(20, CGRectGetHeight(cell.frame) / 2, 200, 50)]; titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey]; titleLabel.backgroundColor = [UIColor clearColor]; [cell.contentView addSubview: titleLabel]; }

  • What technologies to use for a particle system with enormous calculation demand?

    - by Amir Rezaei
    I have a particle system with X particles. Each particle tests for collision with other particles. This gives X*X = X^2 collision tests per frame. For 60f/s, this corresponds to 60*X^2 collision detection per second. What is the best technological approach for these intensive calculations? Should I use F#, C, C++ or C#, or something else? The following are constraints The code is written in C# with the latest XNA Multi-threaded may be considered No special algorithm that tests the collision with the nearest neighbors or that reduces the problem The last constraint may be strange, so let me explain. Regardless constraint 3, given a problem with enormous computational requirement what would be the best approach to solve the problem. An algorithm reduces the problem; still the same algorithm may behave different depending on technology. Consider pros and cons of CLR vs native C.

  • How to separate model and view with Core Data?

    - by andrewebling
    I have a subclass of UIView which draws itself based on data held in a corresponding model class, which is a subclass of NSManagedObject. The problem is, some fields in the data model (e.g. the position of the view) are already held in the view (i.e. the frame property in this case). I then have a data duplication/synchronization problem to solve. To complicate matters further, the view needs to update in response to changes made to the data model and the data model needs to be updated in responses made to the view (e.g. the user dragging it to a new location). What's the best way to solve this? Using KVO and references in both directions? Or is there a better approach?

  • Where is Python support for PEM + RSA + DES3?

    - by jasonjs
    I need a Python library that supports PEM files and both RSA signing and DES3 encryption. pycrypto doesn't seem to support PEM, and its mechanism for loading existing keys is undocumented and cryptic. m2crypto doesn't seem to support DES/DES3, oddly. I've been running an openssl subprocess, but I'd rather have something built in and preferably fast. Does this exist? (Failing that, I hesitate to ask, but are there high-level enough C apis available for this that I could write a special-purpose extension without killing myself/introducing vulns?)

([TimeStamp] < GETDATE()-0 and ([TimeStamp] > GETDATE()-31) But I want to see how much value added on over the course of the month. So it started at 21 and went to 44. So I would expect this example to to return 23 (as in 44-21). How would I build a query like this?

  • Is JSONRequest a global Javascript object ?

    - by Anth0
    My goal is to asynchronously call a URL via POST request (REST Webservice) to increment a statistic on one of my object. I am a newby web developper and I discovered JSON yesterday. Since JSON seems a lot popular and handy I went to www.json.org and discovered a JSONRequest object which seems to able one to send POST/GET request asynchronously but I can't get it work. Is it a global Javascript object or do I need to add some files ? I am a little bit confused since I've found a Firefox plugin extension for JSONRequest but I don't understand its purpose.

  • ClickOnce File will not associate on open from web browser download

    - by mstrickland
    I have a ClickOnce program that associates with a given extension and that works fine if the file is located on the file system. My problem comes in when this file is downloaded from a website. I have a web handler that prompts the user to Click to download the file. Upon clicking the link the user is presenter with an Open or Save Dialog. If the user chooses Open the program will not launch. If the user saves the file to their hard drive and then clicks the file the association will work. Any advice on getting the association to work on the prompt when the user clicks Open or is a Save required? -Edit : Tested this on both IE8 and Chrome with same result.

  • PHP: Find total number of images having same name in a folder.

    - by Muhammad Sajid
    Hi, I am creating code to upload images in a folder using PHP, & before upload an image I check that if any image with same name already exists in the folder by using below syntax: if (file_exists('profilephoto/' . 'frame.gif')) { } But actually I don't want to restrict the user to upload more images with same name & obviously it is impossible to save two images with same name , but there is a way to just find total number of images with same name & upload the next image with appending total number + 1 with image name. Now I just want to know that using PHP how could we find total number of images having same name in a folder? Thanks.

  • How to get information about a Windows executable (.exe) using C++

    - by ereOn
    Hi, I have to create a software that will scan several directories and extracts information about the executables found. I need to do two things: Determine if a given file is an executable (.exe, .dll, and so on) - Checking the extension is probably not good enough. Get the information about this executable (the company name, the product name, and so on). I never did this before and thus am not aware if there is a Windows API (or lightweight C/C++ library) to do that or if it is even possible. I guess it is, because explorer.exe does it. Do you guys know anything that could point me in the right direction ? Thank you very much for your help.

  • Is there a script that can dynamically list the contents of a folder?

    - by user294756
    I am redesigning my company's intranet site in Wordpress and one of the things they need is an archive of company memos. There are over 300 memos saved in one location and I'm wondering if there is a jQuery script that I can run that will read the contents of a local (network) folder and auto-generate a list of the contents of that folder dynamically (and generate those names as a hyperlink to that file, but if I can list the files, I can get include the hyperlink tag myself). I can always manually create the list of hyperlinks (would take a couple days to do so) but if I can generate it dynamically, whenever a new memo is added, the script will automatically include it making the site much easier to maintain. Is this at all possible? I know that this can probably be done in PHP, but the page I need to do this on is not a php page, it is one of the subpages that is created in wordpress that does not have a php file extension and can't run php code (that I know of) Thanks in advance for any and all assistance.

  • Worth it to use jQuery UI hosted by Google?

    - by chobo2
    Hi So I heard good reasons why to use the jquery hosted on google because of caching. But I am not sure about jQuery UI though. I am guessing that the jQuery UI file hosted on google has every single extension and plugin (such as Draggable, etc). So is that not kind of a waste if say your only using only jQuery UI tabs? to get all that other stuff with it. Also I see they have some of the templates up for the css files. I am guessing the caching would be the main advantage of using the hosted file.

  • Proper use of use of "cor" function in R

    - by order
    I am interested to know what a proper x (vector matrix or data frame) input looks like. I am currently using the function in two different sorts of matrices. However, I am not sure how R would interpret my data the way I intend. I will explain the types of matrix by example. Type 1 Gene1 Gene2 Gene3 sample1 sample2 Type 2 Sample1 Sample2 Sample3 gene 1 gene 2 gene 3 Are either of these formats valid x parameters? I input both of types of matrices and get some results, but without knowing whether or not this a proper use the function, these are just random numbers. Thank you for your time. I apologize that this isn't more interesting.

  • Image animation stops on minimizing and restoring

    - by lc
    I have a .NET WinForms application with an animated GIF in a PictureBox. It's a loading animation, shown while a BackgroundWorker does some processing in another thread. I load the image by setting the Image property and it animates on its own. All is fine until I minimize and restore the application. At which point, the image stops animating and just displays whatever frame it was last on. Note that: The background thread still runs fine and none of the "business" of the application is affected. Subsequently-displayed animated GIFs do work fine (unless the application is minimized again). Does anyone know what causes this problem? Any workarounds?

  • Magento module - database not initialized?

    - by Magnus
    Hello, So I've installed an extension in my Magento Enterprise. I've been able to configure new options in the admin interface after installing the module. However in the frontend it complains "table not found". Checking the database that is indeed true. Seems the mysql4-*.php scripts have not been run or failed. Is there a log or something I can look at to see what goes wrong? From what I've read (difficult to find documentation on this) the modules db should've been initialized on the first request after it was installed and activated. Any other suggestions to what I can check to find out why it's not initialized properly?

  • SWIG interface file questions

    - by morpheous
    I am writing a C/C++ extension module for other languages and I am using SWIG to generate the bindings. I have two questions Can I include more than 1 header file in the declaration part of the interface file e.g.: /* Declarations exposed to wrapper: */ > %{ > #define SWIG_FILE_WITH_INIT > #include "a.h" > #include "b.h" > #include "c.h" %} In all of the examples I have seen so far, after the header include declaration (as shown above), the functions declared in the header are then declared again in the interface file. Is this really necessary, as it means there are two copies of the function declarations that need to be maintained. Note: I can appreciate that some functions/methods declaration may need to be 'decorated' with the 'newobject' declaration so these obviously need to be in the interface file, to avoid memory leaks - however, I would have though that it would be sufficient to include the headers and then ONLY the declarations of the functions/methods that need to be declared with 'newobject' - is this recommended way of doing things?

  • Get standard application for txt files (.NET)

    Possible Duplicate: Finding the default application for opening a particular file type on Windows Hello, in my application I want to open a text file, which has no .txt extension. Is there any way to get the standard application for .txt files in .NET (C#)? Sure I could use "notepad", but there might be some people (like me), who prefer another (their standard) editor. Thank you very much. Edit: The registry key "[HKEY_CLASSES_ROOT]\txtfile\shell\open\command" references notepad, but that's not my standard app for txt files. How do I get the my current standard app for .txt?

  • View is moved 3 pixels

    - by Jakub
    Hello, In my app I move the table view (in order to make the text fields visible when the keyboard appears). The view is looks following: This is the code I use for resizing the view and moving it up: static const NSUInteger navBarHeight = 44; CGRect appFrame = [[UIScreen mainScreen] applicationFrame]; tableView.frame = CGRectMake(0, navBarHeight, appFrame.size.width, appFrame.size.height-navBarHeight-216); //216 for the keyboard NSIndexPath *indPath = [self getIndexPathForTextField:textField]; //get the field the view should scroll to [tableView scrollToRowAtIndexPath:indPath atScrollPosition:UITableViewScrollPositionMiddle animated:YES]; The problem is that when the view is moved up it also moves 3 pixels into right direction (it is hard to see the difference in the screenshot, but it is visible when the animation is on and I measured the difference with PixelStick tool). Here it is how it looks after the move: My analysis shows that scrolling the table does not influence the move to the right. Any ideas what is wrong in the code above that makes the view move to the right?
